How Important is a Solar Inverter?

In the relentless pursuit of cost-effective and sustainable energy, nothing has more potential than the sun. At least in theory, it can meet the global energy demand for a whole year. This is a lot of energy. The challenge is to figure out how to harness that energy efficiently and effectively.

Solar inverter is an important part of solar power generation system. It converts all direct current generated by solar panels into alternating current, which can supply power to anything that needs power. Without inverters, the power collected by solar panels would have nowhere to go. Not only that, the inverter is also the brain of the solar system. It provides ground fault protection and overall performance statistics. If there is a problem with your system or a particular panel, it is likely that your inverter will detect it. Solar inverters also play a huge role in the efficiency of the solar system. When energy is transferred from solar cells to your home or business, it will inevitably lose some energy. An efficient inverter minimizes these losses. The more efficient your inverter is, the less batteries you need to generate the power you need, reducing the overall cost of the entire system.

Solar energy uses photons released by the sun to generate electricity. Photovoltaic (PV) solar panels consist of multiple solar cells, essentially miniature conductors. Each cell has a positive electrode and a negative electrode, which together form an electric field. When photons strike the solar cell, electrons break free from the atoms and flow in one direction along the circuit. This unidirectional current is called direct current or DC. Each solar panel has a plurality of solar cells, which can be connected together to form an array. The more batteries and panels you have, the more energy you can collect and deploy. With unlimited solar cells, you can create unlimited direct current.

However, the power grid and most commercial appliances were made to run on alternating current, or AC. With AC electricity, the loose electrons don't just flow in one direction, they periodically reverse direction when pushed or pulled by some form of energy. For solar power to be useful in providing electricity to run our homes, businesses, and cities, the DC power must be converted to AC power. This is why it's important that all households planning to install solar panels also plan to buy solar inverters.
